摘要： An improved magnetic recording medium is disclosed, particularly a magnetic tape suitable for sound recording and video recording, which comprises as a recording element a mixture of cobalt-containing iron oxide magnetic particles consisting essentially of ferromagnetic iron oxide particles containing cobalt and optionally a divalent iron in the most outer layer thereof, and .gamma.-ferric oxide particles in the ratio of 10:90 to 50:50 by weight, said mixture of cobalt-containing iron oxide magnetic particles and .gamma.-ferric oxide particles being applied to a substrate (e.g. a polyester film) with a binding agent. The magnetic recording medium has excellent electromagnetic transducing properties and improved charging properties and is useful for conventional magnetic recording apparatus used at normal position with high sensitivity in wide range of frequency.

摘要： A battery accommodates elements for electromotive-force within a metal case. This metal case is a metal case having a bottom wherein the bottom thickness/side thickness ratio has a value of 1.2-4.0 and has a cylindrical, prismatic or similar shape. The metal case is constructed of a metal material whose chief constituent is aluminum. Furthermore, it is desirable that a multiplicity of shallow grooves perpendicular to a bottom face are formed in at least a battery inside face of the metal case and moreover that a nickel layer is provided on the battery inside face. The metal case is made by DI processing involving drawing and ironing, to have a value of bottom thickness/side thickness ratio which was hitherto unavailable,i.e., 1.2-4.0 can be obtained.
